The hardness of diamond should not be confused with its relative toughness,or resistance to shattering on impact. Diamond is the hardest natural substance,but it is far from the toughest,and in fact it is brittle.If you drop a diamond on a hard surface or hit with something hard,it can crack or shatter.


钻石的硬度不应与它的相对韧性或在冲击时抗碎裂性相混淆。钻石是最硬的天然物质,但它远不是最硬的,事实上它是易碎的。如果你把钻石掉在坚硬的表面,或者被硬物击中,它就会裂开或粉碎。


Because of its softness and its structural weakness caused by the asbestos “horsetail “includsions,the facet edges of demantoid are easily damaged or worn down with repeated use.Because of the lack of durability and the high value of demantoid stones,this is not a good choice for jewelry that gets hard daily use.


由于石棉“马尾”所引起的柔软性和结构上的弱点,使其在多次使用后,其侧面边缘易被破坏或磨损。由于缺乏耐用性和高价值的钻石,这并不是一个好的选择,珠宝得到难以每天使用。

Mix of almandine and pyrope is called rhodolite


铁铝榴石和辉石的混合物叫做红辉石

Vedic astrologist believe hessonite to be powerful talisman to increase longevity and happiness. Ancient Hindus believed hessonite to be fingernails of a great demon


吠陀占星家相信海松石是增加寿命和幸福的有力护身符。古代印度教徒相信海森尼特是一个大恶魔的指甲

Spectacular inclusions of Spessartine, similar “horsetail “of the demantoid


斯珀萨汀的壮观包体,类似“马尾状物”

锆石也很有趣,因为它年代久远。事实上,据我们所知,地球上没有任何东西是古老的。已知地球上最古老的一块是来自西澳大利亚的锆石晶体,其年代在44亿年以前。这个锆石是在收集自然历史博物馆在珀斯,威登澳大利亚。


Zircon is also interesting because of its remarkabley great age.In fact,nothing on earth is older,as far as we know.The oldest known piece of the earth is a zircon crystal from Western Australia,which is dated at 4.4 billion years before present.This zircon is in the collection of the natural history museum in Perth,Weetern Australia.

Melanite is the darkest form of andradite, color due to trace of elements-titanium, sometimes reffrred to as titanium andradite, used in mourning jewelry during the Victorian era. melanite occurs in volcanic and metamorphic rock


在维多利亚时期,黑色素是铁镁榴石中最黑的一种,由于含有微量的钛元素,有时又被重新加工成钛和镁榴石,用于哀悼珠宝。黑云母产于火山岩和变质岩中

葡萄石-强烈的祖母绿的品种含有微量的钒。在富含钙的轻度变质岩中,葡萄石通常形成粗短的棱柱形到锥体端部的板状结晶。


Uvite-intense emerald-green variety containing trace of vanadium.Uvite is usually found in lightly metamorphic rocks that are rich in calcium,and it forms stubby,prismatic to tabular crystals with pyramidal termination.

马拉维的一些物质也有轻微的褐色,但这可以通过温度为700℃的热处理来去除。工艺将石黄的次级颜色与原黄颜色相匹配。热处理后的石头是完全稳定的,纯黄色看起来是不可逆的。巧合的是,进口的马拉维石材偶尔会有明显的柠檬膨胀,以配合它们的柠檬黄颜色。这是因为矿工们经常将水晶在水中和柠檬汁中煮沸,以溶解刚从地下挖出的石头表面的空白涂层。价格不会改变石头的颜色。酸性柠檬汁只是帮助溶解碱性涂层。据称,马拉维的Tumbuku矿有雇员,他们的唯一工作是为加工过程采购和榨柠檬。在美国和其他地方与马拉维金丝雀合作过的切石机说,它切割和打磨时散发出淡淡的柠檬气味。


Some of the Malawi material also has a slight brownish tinge;but this can be removed by heat-treating the stone with temperatures of about 700℃.This process turns the secondary color of the stone yellow to match the primary yellow color.The heat-treated stones are completely stable,and the pure yellow color appears to be irreversible.Coincidentally,imported rough Malawi stones occasionally have a noticeable lemon swell to go with their lemon-yellow color.This is Because the miners often boil the crystals in water and lemon juice to dissolve a blank coating that covers the stones when newly removed from the ground.The price does not alter the color of the stone.The acidic lemon juice simply helps dissolve the alkaline coating.The Tumbuku mine in Malawi was said to have employees whose sole job is to procure and squeeze lemons for the process.Stonecutters in the United States and elsewhere who have worked with Malawi canary material say it gives off a faint lemon odor when it is cut and polished.

Zircon is defined by the chemical composition ZrSiO4,and it has been used for nearly all colors of Zircon at one time or another.Here we follow a more restricted definition for this variety,including only reddish-brown,Brown,red,and orange Zircon as hyacinth,and excluding yellow,blue,green,and colorless hues.


锆石的化学组成ZrSiO4定义了锆石,并在不同的时间被用于几乎所有的锆石颜色。在这里,我们遵循对这个品种更严格的定义,只包括红棕色,棕色,红色和橙色锆石象风信子,排除黄,蓝,绿,无色的色调。

帝王黄玉被认为起源于19世纪的俄罗斯,在乌拉尔山矿坑首次被发现。当时,粉红色和红色的黄玉据说是专为沙皇家族保留的,这就是为什么它被称为“帝王”黄玉。


The name imperial Topaz is thought to have originated in nineteenth-century Russia,in the Ural Mountain mines where it was first discovered.At that time,pink and red Topaz were said to have been reserved exclusively for the family of the Czar,which is why it is called “imperial”Topaz.

Topaz is the hardest of all silicate minerals.  A recent trend in the jewelry trade is an iridescent-colored stone called “Mystic-Topaz”that display many colors.The unusual color effect is not natural and is the result of applying a thin coating of Titanium Oxide to the surface of the stone.Although topaz is hard gemstone,it is also somewhat BRITTLE or SHATTERED with a hard blow.


黄玉是所有硅酸盐矿物中最坚硬的。最近的趋势,珠宝贸易是一个彩虹色的石头称为“神秘黄玉”,显示许多颜色。这种不寻常的色彩效果是不自然的,是由于在石头表面涂了一层薄薄的氧化钛。虽然黄玉是坚硬的宝石,它也是有点脆或粉碎的一个沉重打击。

世界上最有价值的颜色是一种强烈的深红色,通常被称为鸽子的血红色。世界上最有价值的宝石之一是CARMEN LUCIA红宝石。今天的关键词-深红色,铬,橡木,卡门露西亚红宝石


The most valuable color in the world is an intense CRIMSON color commonly called PIGEON BLOOD red.One of the world’s most valuable faceted fine rubies is the CARMEN LUCIA ruby. Today key words-crimson ,chrome,kermes oak,Carmen Lucia Ruby

The most valued blue sapphires are neither very dark nor pale,they are a soft,velvety, vivid blue shade called “cornflower blue”or “Kashmir blue”.


最珍贵的蓝宝石既不是很深也不是苍白,他们是一个柔软,天鹅绒,生动的蓝色阴影称为“矢车菊蓝”或“克什米尔蓝”。


In the sixteen century,a common folklore was that colorless sapphire was a form of unripe ruby,and that if it was left to mature,it would one day become a red ruby


在十六世纪,人们普遍认为无色的蓝宝石是一种未成熟的红宝石,如果任由它成熟,总有一天会变成红宝石。”
